Running 265/35/18 tires on Apex Arc8 18x10et25??

I have new set of Hankook 265/35/18 RS3 that I was going to run on a 18x9.5 wheel for the occasional track/mostly daily but now I want a set of Apex Arc8 18x10 et 25. I know it will fit but will it be safe for the track (Willow Springs). I know most run 275 but seeing if 265 could work so I can burn through this set before I order new rubber.

mfg recommendation rim size for 265/35/18 is 9.0 to 10.5 inches, so your 10 inches rims should be okay

You should expect to need spacers in the front.

18x10" ET25 rims have a known issue with KW coilovers (V3 and clubsports) and inner barrel clearance. I believe a 5mm spacer should be sufficient for clearance with this setup.

Okay - thanks! Do TC Kline's have this issue too? I am just about to pull the trigger on these (They are selling at a ~$950 discount right now)

That is correct, a 5mm spacer would be needed for wheel clearance from the progressive V-shaped springs of the KW V3's, and the lower spring perch of the KW Clubsports due to the helper spring. The 18x10" ET25 can surely be used with a 265/35/18, though the preferred tire fitment for the e9x M3 is 275/35/18 to gain more traction and utilizing the 10" width a bit better.

TC Klines should be utilizing a linear race spring on their coilover system, so there should not be any issues with the 18x10" ET25 fitment.
